new here, a question...

I am about to switch to the EVO after a year and half with Diamond. I been searching for three hours, and can't seem to find out, 'is there a .zip file reader/zipper available for android, or even a functional file system for that matter? I'm used to winmo and having winzip and pocket rar. TIA
